Processing: Image acquisition with Canon EOS Utility. Automatic image set processing (calibrate, align, and combine) with ImagesPlus v3.75. Levels, curves, unsharp mask, and crop in Photoshop.
* In addition to the forty 5-minute images, I took twenty 10-second images and blended them into the deeper image to restore the saturated core of the nebula.
This is the first light image for my AP900GTO mount.
